In this paper, we study on making a use of value-added services using DTV closed caption data. Note that Closed-Captioning service helps to bridge "digital divide" through extending broadcasting accessibility of a neglected class such as hearing-impaired person and foreigner. In Korea, DTV Closed Captioning standard was developed in June 2007, and Closed Captioning service should be provided by an enforcing law in all broadcasting services in April 2008. Here, we describe the method of extracting a caption data from MPEG-2 Transport Stream of ATSC-based digital TV signal and generating a caption file using the extracted caption data and time information. In addition, we present the segmentation method of broadcasting content using caption file. Experimental results show that implemented S/W tool provides the feasibility of the proposed methods and the usability of closed caption for a variety of data application service.

A change of social environment based on digital information technology has decreased the disparity of regional cultures by exchanging & consuming contemporary information & culture freely. After 1995, when local autonomous entity system was established, the local autonomous bodies competed with one another in developing the regional society with its' own resources, human powers & cultures, independently of the central government. In the competitive system, a local government is getting itself distinguished from each other in the cultural & regional properties, and brands the region with its unique events, public relations(PR) & development strategies. The environment for advertisement has changed rapidly under the spontaneous system of regional brand and competition, which means the changes of creative standard in the field of advertisement. An in-depth advertising creativity with induced impression & trust is one of the most important aspects of the advertisement to become persuasive to the public effectively. This demand has had public advertisements changed rapidly and the change of regional system's advertisements has started already. This study focuses on analyzing the status of Local Government's commercials on TV, and presenting an effective method for improving it.

The purpose of this study is to investigate elementary school students' understanding the concept and operations of decimal fraction. The survey research was performed for this study. This survey was done by selecting 156 students. Questionnaire were made in five areas with reference to the 2007 revised mathematics curriculum. Five areas were the concept of decimal fraction, the addition, the subtraction, the multiplication and the division of decimal fraction. The results of such analysis are as follow: The analyzed result of understanding about concepts and operation of decimal fraction showed a high rate of correct answer, more than 85%. Students thought that multiplication and division of decimal fraction is more difficult than addition, subtraction, concept of decimal fraction. As the learning about concepts and operation of decimal fraction progress, the learning gap is bigger. Effort to reduce the learning deficits are needed in the lower grades. Mathematics is the study of the hierarchical. Learning deficits in low-level interfere with the learning in next-level. Therefore systematic supplementary guidance for a natural number and decimal fraction in low-level is needed. And understanding concepts and principles of calculations should be taught first.

This paper analyzes if the rapidly increasing cyber universities' remote education provides services based on web accessibility standard and suggest the direction to reduce information difference between people. It selected 10 cyber universities recognized by the government and analyzed the application situation of the web accessibility using' A-Prompt', an evaluation and analysis tool for web accessibility focusing on factors that can be evaluated technically. It also compared it with $\ulcorner$cyber universities remote education web accessibility result$\lrcorner$ performed in 2006 to confirm if the accessibility is improved according to 'web contents accessibility instruction (KWCAG) 1.0. The result shows that the items such as the use of text and the support of supplementary explanation tool have improved. But it was analyzed that it is difficult for people to use web contents provided by domestic cyber universities. So the educational contents' accessibility application must be considered to solve such problems and publicize the remote education.

Since the 2000s, China has been trying to develop the mid- and western regions and reduce regional disparity between the eastern region and the others by construction of the eight HSR corridors known as 4+4. The high-speed railway is known to have a positive impact on regional economic development by improving accessibility between regions. However, some studies point out that the high-speed railways could worsen regional imbalances. The purpose of this study is to examine the impact of the high-speed railway on regional economic growth and balanced development in China, using the beta-convergence model. In particular, we focused on how the effects of high-speed trains on regional economic development varied depending on the level of development. The analysis was conducted centering on the Shanghai-Chengdu line which is connecting eastern, central and western regions with different levels of development.

To narrow gap of information level and clarify a sense of term between various fields of industry is very important. In this point, these actions including generating, managing and sharing standard terminology are needed and management system for standard terminology is necessary. Nowadays, many research fields and many researchers have studied terminology standardization and tried to share these terminologies with other fields or researchers. But there are little systems which collect terminologies, keep the tracks of changes in terminology standardization, give workplace to specialists and service standard terminology to public. In this research, we propose management system which support a series of processing from registering terminologies to opening standard terminology to public.

Due to the concern of regional unbalance relating to healthcare resources, the government has set up a plan to expand public healthcare services and a policy to manage the supply of hospital beds. However, it is not clear what standards are needed to measure the degree of unbalance, and to what extent the gap needs to be narrowed. Unlike the previous methodology comparing the proportions of patients who move out from their administrative district to receive medical services, this study examines the inconvenience gap patients experience when they have to move out from their actual living area. The logit and multinomial logit models are employed. The regional unbalance decreases when the degree of movement is measured based on the living area. This result implies that essential standard for achieving regional balance relating to medical services need to be based not on the even distribution of medical resources, but the complications of regional people that require proper medical services.
